The statedir patch for 1.6.2 is used in the 9999 ebuild. That patch no longer applies without using patch(1)’s --ignore-whitespace flag, due to a change in indent level.
The -9999 ebuild is nonfunctional right now anyway (upstream svn is offline).
I must have added a /etc/portage/env file to update from my local svnsync copy of the repo; consequently I missed that servepath.com was offline when I switched from 1.5.9999 to 9999. I posted a tar of my svnsync of cups svn at: http://jhcloos.com/t/cups/cups-svnsync.tar.xz in case anyone wants to host it.
Repo is back, well sort of... and this is fixed too.
